Bookologia Indices Dataset
Bookologia is a specialized search engine of books, to find any book within seconds.
This dataset contains three Elasticsearch indices extracted from Bookologia database: authors_data, book_links, and books_data_bis.
Each index stores structured metadata relevant to authors, books, and associated resources.
This dump is suitable for tasks involving metadata analysis, author-book linking, recommendation systems, or search enhancement.
